This week I read two articles that describe growing technologies: one newer, the other well established. The first is the subject of the August 17 Time cover story (US Edition) titled “The Surprising Joy of Virtual Reality: And Why It’s [nearly upon us, better than you think… and] About to Change the World.” Put on those increasingly sophisticated virtual reality goggles and our whole perceptions change. This is not just about making video games more dramatic. It can be about treating the effects of trauma, dealing with various psychiatric disorders, and revolutionizing education. I wonder about its potential for changing how we lead, learn about God, or advertise. And are there dangers that we don’t yet see? Apparently we’ll encounter lots more about this come Christmas shopping season.

Much more familiar are podcasts, recently discussed in a Wall Street Journal article (August 8-9.) We’ve all seen podcasts and webinars, some very sophisticated, which move us beyond radio, television or weekly written blogs like this one. Friends have urged me to replace or supplement this newsletter with audio and/or video posts, especially since these tend to be favored by so many people who like to listen or watch rather than to read.

A good communicator knows the characteristics of his or her audience. Surely this includes knowing how the audience learns or prefers to get information. Most readers of this newsletter are older, educated, and presumably inclined to learn by reading. Like me. Would a different audience be attracted by a podcast or other non-written, video or audio format? What about using both formats?

Experienced bloggers have demonstrated the value of captivating titles, eye-catching images, and succinct introductory sentences. These are more likely to attract and hold readers to the end. Similarly, aren’t most of us grabbed and retained by articulate speakers in attractive settings telling interesting stories with practical implications? Boring podcasts may give us something to hear or watch but they make no more impact than boring blog posts.

Podcasts can be produced relatively easily. All you need is a computer with a camera. I have done these with my classes, replacing long lectures with video clips to be watched at leisure.

Podcasts and webinars can be produced from anywhere and allow feedback so observers are more involved with the action. Should you be doing this? Should I?

Please comment. Tell us how you have used podcasts, webinars or virtual reality.
